Problem displaying results from a SQL database

Hey everyone,
So I am basically fairly new to coding, i am doing a tutorial i found on the web and trying to implement into my own. I have gotten so far in it and now have struck a problem, when i search for a item in a database it wont find it and a previous problem i had was that it was displayin all the records instead of the searched records. Anyway here is my code and i would greatly appreciate any help as i am stuck on it for weeks now trying to change is around and its really disheartening. P.S. The link to the tutorial if its any help is:http://www.sebastiansulinski.co.uk/web_design_tutorials/tutorial/9/link_exchange_system_wi th_dreamweaver_cs3
Thanks
Frank

In your code, you have this -
// Search engine functionality
if ($_GET['make'] || $_GET['model']) {
$key = $_GET['make'];
$categ = $_GET['model'];
$query_rsStock = "SELECT * FROM stock WHERE stock.model LIKE '%$make%' AND stock.model LIKE '%$model%' ORDER BY stock.date DESC";
} else {
$query_rsStock = "SELECT * FROM stock ORDER BY date DESC";
The "else" part of the "if" block is what is selecting ALL the records -
$query_rsStock = "SELECT * FROM stock ORDER BY date DESC";
This means that the "if" part of the "if" block is always failing. When does it fail? Whenever you have not passed a URL variable for either "make" or "model". Are you sure you are correctly passing that variable?

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012
Paul Power
I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.

Formating numbers in a form after retrieving from an SQL database

Hello everyone,
I am using php to populate a form using numbers taken from an sql database. I am having a hard time showing decimal places in those numbers. The code I am using in the value section of the form is:
value="<?php if (isset($_POST['unit_price_1'])) {
     echo htmlentities( $_POST['unit_price_1'], ENT_COMPAT, 'UTF-8');
     } else {
          echo htmlentities($row_getInvoice['unit_price_1'], ENT_COMPAT, 'UTF-8');
     } ?>" />
This code rounds all numbers up and eliminates decimal places. I am trying to show dollars and cents.
How do I alter the code to accomplish what I want.
Jeff

Not sure what might come in your way here, so I just made the following simple test by using a static value rather than one which gets derived from a recordset (the source shouldn´t matter), and this works well for me without seeing the value altered in any way:
<?php
$value = "10.22";
?>
<input type="text" name="whatever" value="<?php echo htmlentities($value, ENT_COMPAT, 'UTF-8'); ?>" />
However,. for displaying numeric values you really don´t need to use htmlentities/ENT_COMPAT etc etc -- that´s something you´d rather use for displaying textual contents containg special characters like umlauts and such.
If all you need is to add some degree of protection by escaping special HTML characters (<, >, &, etc.), the function htmlspecialchars() will only be escaping just these characters and leave the rest "as is", whereas htmlentities() is notably more rigi, because this function will convert all applicable characters to HTML entities -- but again: at this point you´re just *displaying* some numeric value, that is, such security measures are pretty much pointless in this scenario, because there´s nothing to protect from ;-)
Please test what happens when doing away with the htmlentities - thing.
Cheers,
Günter

Generating next number from the SQL database using java

Hi friends, I have a problem and need your help. I am working on a project about submitting claims form through the adobe PDF file and SQL database. I have problem working on a web service (written in java) that will generate the next Invoice Number from the SQL Database table. The field type for the column is text(var char). *Example: I first need to get into the table and search for the last Invoice number in the table and if the last invoice number in the table from the database is 3, i would want to generate the next number which is 4 and filled it up in the PDF file through web service that i am implementing. Can you all provide me some guidelines on how to implement this method in my web service?
Thanks a lot. I need it by today. Hope someone can reply this as soon as possible.
Lim89
Edited by: LIM89 on Apr 2, 2008 7:10 PM

far simpler to use a sequence generator, which most databases support.
Suggested method to get the max value in the column is NOT secure, unless you lock the entire table for update before you do so, which is a severe performance penalty.

How to export the result from executing sql statement to excel file ?

HI all,
Great with Oracle SQL Developer, but I have have a trouble as follwing :
I want to export the result from executing sql statement to excel file . I do easily like that in TOAD ,
anyone can help me to do that ? Thanks so much
Sigmasvn

Hello Sue,
I just tried to export to excel with the esdev extension and got java.lang.NumberFormatException. I found the workaround at Re: Windows Multi-language env, - how do I set English for application lang?
open the file sqldeveloper\jdev\bin\sqldeveloper.conf and add the following two lines:
AddVMOption -Duser.language=en
AddVMOption -Duser.country=USyet now my date formats in excel are 'american-style' instead of german. For example 01-DEC-01 so excel does not recognize it as date and therefore I can not simply change the format.
When export to excel will be native to 1.1 perhaps someone can have a look at this 'feature'

Trouble displaying results from a database call

Hi Everyone,
I have written a JSP page that sends and receives information to a MySQL database. It is not completely functional unfortunately. The first section of the page that is responsible for updating a database table works fine. However when I go to retrieve information from the same database table something is going astray.
I feel that I am doing something wrong with regard to the ResultSet object. Please see the bottom of the code section below. Ultimately this code only displays beach_percent as Zero, no matter how many entries there are in the database table for the corresponding value of Beach & Sea Stamps.

Hi,
One reason could be of spaces .Before checking in the loop use trim function on the data retrieved from the database. You can also debug using System.out.println.
Also just a suggestion - it is always a good coding practice to declare the variablse outside the loop. Don't declare the variables within a for loop.

Is it possible to load SWF files from an SQL database?

Hi all, I am very new to flash (I am primarily a C'# developer!) and I have been asked to investigate the possibility of doing the following;
Create an application that allows swf files to be uploaded and stored inside of a SQL database as binary data (Why a database is a long story!)
Allow this binary data to be extracted via a http request to be dynamically loaded inside of a web page.
Now the first part was easy. I have all of my swf's uploaded and stored inside of the database. I have code that can make a request for the binary and write it to the response, so far so good. Now this is where I am stuck.
I thought I could dynamically load the swf binary data by creating a very basic swf that simply contains a movie clip holder and for now a simple loadMovie statement. My idea being that I can could provide a url for the loadMovie statement that returns the swf binary data. This is where I have ground to a halt.
I can see the call being made from the swf, I can see the data being returned but I cannot get it to render. I remember seeing an article some time agao where someone stated that they had used this method with success but I cannot find now. Has anyone ever done anything like? Is it even possible? Am I missing something simple?
I have tried to return both the raw binary data and also used response.write but to no avail. Can anyone help?

You are possibly trying to load AS3 swf into an AS2 Container at least the use of loadMovie() points in that direction. Be sure to use AS3 and target at least Flash 9 in your Loader/Main.swf. Also the AS3 concept of how to load swfs differs a lot from the old concept.
Look into the docu:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/Loader.ht ml
But the biggest Problem seems to me -what you mentioned- that Loader needs a (defined) URLRepuest and since your swf files have no "real" URL and you surely don`t want to let the user directly write to your server, a workaround would be to write the BinaryStream with AIR-functionality to a local installlation directory and load it then from there.

UUT Result log in SQL database?

Hello All
I am facing a requirement where i want to log results of sequence execution[only the complete seq result and NOT step results] to SQL database BUT as and when the UUT_ID varies the entry should be made into a new column with the same name as UUT_ID. As of now whenever i execute a sequence with different UUT_ID, a new row gets added as a result.
Please reply back with your suggestions asap, as this very urgent for me :-)
Regards
Nitin Goel

But in my opinion, that's just a way to display the results - not a way to store the data. I also have thousands of test cases and tens of thousands of different UUT each month. Each UUT has a separate record (a unique row) and yet if I design a proper query and report format, I can show the results exactly like you have. The design of a relational database should not be the same as a report design, imho.
A database is designed to have unlimited rows (dependent only on storage space). I'm not sure a db can have unlimited columns. That would be something you could check with your dba. Dynamically adding a new column and doing an update to an existing row would probaby be much slower than just doing an insert.

Can anyone help me plz?
Thnx in advance.

Hello,
It is very difficult for us to "guess" what images you can read and what others you cannot.
Maybe you could provide more information on images that are not displayed ?
What is their native format ?

Is it possible to migrate WebCenter Portal data from a SQL database to an Oracle database?

We have our WebCenter Portal applications set up using a SQL database. Now we're wanting to migrate to an Oracle database and I'm wondering if that is possible.

Yes it should be possible though i have not tried it myself. You basically export a file from mds ( xml) and import it into oracle db.
Thanks

Problem returning variables from dynamic SQL/PLSQL

Hi, I have a problem I am trying to solve using a very short piece of dynamic SQL or PLSQL but I am having problems getting the variable values out of the dynamic block.
I have 16 counters whose names are made up of three variable parts - 'scheme', 'contributory category' and 'employment category'
The 'scheme' can be either 'no1', 'no2', 'off', 'cg' or 'amc'
The 'contributory category' can be either 'cont' or 'noncont'
The 'employment category' can be either 'ft' or 'pt'
(There are only 16 because only 16 combinations are possible)
For example the total counter name could be 'v_cg_noncont_ft_count'
I have created a variable by concatenating the various elements called v_incr_count_name which holds the name of the counter I want to increment.
I am running this whole thing within an anonymous PLSQL block so I cannot use global variables meaning that my variables are not visible within a dynamic PLSQL block.
I believe this means that either I need to bind the variables within a PLSQL block or use a SELECT FROM INTO SQL block.
I have tried a few solutions with no luck such as the following PLSQL:
v_incr_count := 'v_'||v_scheme||'_'||v_cont_cat||'_'||v_emp_cat||'_count';
sql_stmt := 'BEGIN :a := :a + 1; END;';
EXECUTE IMMEDIATE sql_stmt USING v_incr_count_name;
Unfortunately I am getting the 'IN bind variable bound to an OUT position' error which I believe is because it is trying to return a value into v_incr_count_name which has been defined by default as an IN variable. The problem is that I need to store the returned value into the variable whose name is stored in v_incr_count_name.
Another solution I tried is:
v_incr_count_name := 'v_'||v_scheme||'_'||v_cont_cat||'_'||v_emp_cat||'_count';
sql_stmt := 'SELECT '||v_incr_count_name||' + 1 FROM DUAL';
EXECUTE IMMEDIATE sql_stmt INTO v_return;
This solution gives me an 'Invalid colum error'
Any help would be greatly appreciated
Cheers, Dan

How to use java to create an XML document from an SQL database?

Hi,
I'm a complete novice at XML and have only recently started programming in Java.
I'm currently trying to develop a package in Java 1.1.8 which requires a set of very specifically formatted XML documents. These documents would need to be updated regularly by people with no knowledge of Java and I would like to make it as simple as possible.
Since the data will already be in an SQL database, I thought it might be possible to generate the XML documents from the data using a small Java application, but I'm not too sure how to go about this or if this is even possible! Any help or pointers in the right direction would be very much appreciated.

Do you have the option of upgrading to a newer version of the JDK?
JAXB does what you are wanting very easily. Also there are tools if you don't want to write your own. JAXB is available as early release on Sun's site as is the newest JDK. Otherwise, you have to design a factory and interface that will do this for you (which is what JAXB basically is in a very simplified view).
